During the winter pepper growing season, it is often attacked by cold currents. The temperature suddenly drops and the seedlings are vulnerable to freezing. The severity of frost damage in seedlings is also related to the speed at which the temperature rises after low temperatures. If the temperature is raised and the thawing is too fast, the seedling tissue may be dehydrated and dried, causing dead seedlings. Pepper seedlings antifreeze measures have the following four aspects. Improved methods: The use of artificial temperature-controlled seedling raising methods, such as electrothermal hotbeds and industrialized seedlings, is the fundamental measure to solve the freezing problem of seedlings. Enhance the cold resistance of seedlings: Avoid seedlings and leggy, remove cover as much as possible before the onset of the cold current, and let the seedlings shine more light and exercise. During periods of low temperatures in rain and snow, use weather as much as possible to clear the gap and remove the straw curtain so that the pepper seedlings are exposed to sunlight. When the rain and snow stopped suddenly, it was clear before and after noon that a few grass curtains were placed on the seedbeds to prevent the seedlings from dehydration and wilting. Bed soil moisture is high, seedlings susceptible to frost damage, so control the seedbed watering before the onset of the cold wave, bed soil too wet to sprinkle a layer of hay wood ash moisture. Balanced fertilization: increase the application of phosphorus and potassium fertilizers, use cold resistance at the seedling stage. Seedlings sprayed with 0.5%-1% brown sugar or glucose water can enhance cold resistance. Spraying 2 times (with 7 days interval) of 0.5% calcium chloride solution in the 3-4 leaf stage can enhance cold resistance. Insulation and antifreeze: Closely cover the seedbed during the cold wave. When ventilation is performed for a short period of time, cold air must be prevented from directly blowing into the bed. Cover straw at night. The straw leaves can be sprinkled on the seedlings and cleared after the cold wave. The straw curtain on the seedbed should be dry. After the snow stopped in the snow, the snow was cleared out of the nursery.
